Competency Evaluation

The development of information technologies changes the learning process. The amount of publicly available data of e-learning systems allows personalized studies. Therefore, the tutor sometimes is needed for the student’s evaluation and consultation only. To ensure clear evaluation requirements and objective evaluation process, the learning material, as well as the evaluation system, must be discrete and semantically expressed. The list of mastered competencies and skills is more important to the enterprise; therefore, during the last years, the study process has concentrated on competency evaluation too. However, the current practice, when students’ competencies are summarized and expressed as one quantitative metric (score), do not express the list of students’ competencies and their level. To solve the problem, in this paper, we proposed a method for the design of competencies’ tree. The competency tree has to be formatted based on context modeling principles and analysis of Scope-Commonality-Variability. The usage of competency tree for students’ competencies’ evaluation proposes clearly defined and semantically expressed evaluation method for both human and e-learning evaluation process. This paper presents the results of the empirical experiment to adapt the proposed competency tree design and application for competencies’ e-evaluation method, based on flexibility, adaptability, and granularity of learning material.

Study Process

An increasing number of educational institutions in the study process uses one of the e-learning systems. Consequently, more and more students are offered learning materials in electronic format. E-materials in distance learning and e-learning is one of the most important elements, therefore much attention and enough time should be paid for their development. There are a number of studies on e-learning quality, where criteria of quality are discussed in the context of chosen e-learning environment and the process of implementation. This article examines only the quality of e-material. The aim was to find a way to reduce the effort and time of electronic learning material quality evaluation. The study used content analysis by summarizing the most important factors influencing the quality for teaching materials. Based on the quality criteria mentioned in the literature and personal experience, a criterion, which affects quality of e-learning material, were summarized and grouped. The criteria were grouped into four groups resulting from didactic, media, usability and formal quality. Quality evaluation is performed by using one of the methods used in software engineering - checklist. Based on the identified quality criteria a checklist was established. In order to facilitate the evaluation process a web-based tool is offered. The tool includes a defined checklist with assessment rating scale and three levels of impact. Evaluation of material quality is shown in the terms of percentage. After testing the tool, it could be used for course developers, program managers or other persons involved in evaluation process of e-learning resources.

Abstract In the field of machine vision, image edge detection is an important technology, which can make necessary preparation for the later image processing. Consequently, accurate evaluation of the edge detection effect of the processed image is a more critical technology. In this paper, the new three criteria are proposed, which is based on Canny's three criteria for edge detection. Through theoretical analysis, three quantitative basic evaluation indexes are given to the new three criteria, namely SSIM index of image reconstruction similarity, BIdx index of edge reliability and CIdx index of edge continuity. Additionally, noise evaluation criteria is also considered. Then the four basic evaluation indexes are fused to get the objective evaluation index EIdx of image edge detection.Finally, the experimental data show that the accuracy of the method is better than that of the subjective evaluation system.

In this study, the failure mechanism of crumb rubber–asphalt pavement was analyzed under the combined effects of low temperature, water, and traffic load. The investigation was carried out based on the mechanical and deformational properties of crumb rubber–asphalt mixture and the typical environmental and load conditions such pavement is typically exposed to. A method was proposed for objective evaluation of the interfacial adhesion between rubber crumbs and asphalt through consideration of the effects of the characteristics of the materials and the working environment. The main evaluation method used herein included the indirect tensile strength test under freeze–thaw–boiling cycle, and the Cántabro abrasion test under water-immersion was adopted as an auxiliary method. The evaluation system has the advantages of simple implementation, realistic simulation of the actual working state of the mixture, and reliable results. Moreover, it is a durability evaluation method that can be specifically applied to asphalt mixtures with some special aggregates or stone mastic asphalt (SMA) mixtures.

This article aims to shed the light on challenges that Palestinian university faced during COVID-19 pandemic. The technology and the digital environment are becoming part of our lifestyle. The whole world has been asked to change the way we work and live during COVID-19 pandemic. No more students sit in the classroom and listen only to lectures these days. Nowadays, education is interactive and engaging. Teachers are doing their best to approach instruction with technology being the mediator in the classroom. Digital transformation is a fundamental process in the knowledge society where information technologies play a vital role in helping students to produce knowledge and process information to meet the ever-growing demands of students, faculty and campus to create a learning environment where everything connects, therefore the efforts of universities, especially arab universities, began to digitize the learning process. As a result of this education Palestine universities has transformed into a rapid, and simple digital education, as the COVID-19 system resulted in the rise of e-learning on an unprecedented scale. Some challenges presented like: lack of strategic plan, digital inequity, technology infrastructure. We recommended the presence of instructional designers and the necessity of the continues evaluation process.

Tree Transformation

The COVID-19 pandemic and quarantine have forced students to use distance learning. Modern information technologies have enabled global e-learning usage but also revealed a lack of personalization and adaptation in the learning process when compared to face-to-face learning. While adaptive e-learning methods exist, their practical application is slow because of the additional time and resources needed to prepare learning material and its logical adaptation. To increase e-learning materials’ usability and decrease the design complexity of automated adaptive students’ work evaluation, we propose several transformations from a competence tree-based structure to a graph-based automated e-evaluation structure. Related works were summarized to highlight existing e-evaluation structures and the need for new transformations. Competence tree-based e-evaluation structure improvements were presented to support the implementation of top-to-bottom and bottom-to-top transformations. Validation of the proposed transformation was executed by analyzing different use-cases and comparing them to the existing graph-to-tree transformation. Research results revealed that the competence tree-based learning material storage is more reusable than graph-based solutions. Competence tree-based learning material can be transformed for different purposes in graph-based e-evaluation solutions. Meanwhile, graph-based learning material transformation to tree-based structure implies material redundancy, and the competence of the tree structure cannot be restored.
